At Solaris (National Synchrotron Radiation Center , Kraków ) we have deployed test VDI software to virtualize physical desktops in the control room to ensure stability, more efficient support, system updates, and restores. The test was aimed to accelerate the installation of new work places for the single users. Horizon software gives us an opportunity to create roles and access permission . VDI software has contributed to efficient management and lower maintenance costs of virtual machines than physical hosts. We are still testing VMware Horizon 7 at Solaris.
